CF2002 intelligent integrated transmitter

Overview

The integrated absolute/pressure transmitter uses high-precision and high stability diffusion silicon isolation sensor components, which convert the absolute or gauge pressure of the measured medium into a 4-20mADC standard electrical signal through highly reliable amplification circuits and precision temperature compensation. Exquisite packaging technology and perfect assembly process ensure the excellent quality and optimal performance of this product. This product has the characteristics of complete variety specifications, standardized interface forms, and convenient zero and range adjustment, which can meet the needs of customers to the maximum extent. The CF2002 integrated transmitter series can be widely used in various harsh and dangerous places in industrial sites.
